Prety much anything you could think up could be done given planeset limations and the will of the map maker to make it hapen. Prety Much by the time of the Invashion of japan, post Okinawa, or later than say Aug. of 45 all Japanese air assests would of Been on Japan, except those in Korea or Formosa/China/ or SE Asia, realy though even the planes in Korea, Northern ChHina were whiped out twhen the Soviets invaded, so you left with Just mainland Japan, and prety much the same plane set we have on Okinawa, except you want a P51 which is like almost 85-100mph faster than an A6M5.
